珍稀濒危植物膝柄木苗期施肥试验

目的]探讨施肥对膝柄木苗木生长的影响。方法]以膝柄木容器苗为试验材料,研究不同肥料组合对1年生苗高度和地径的影响。结果]与对照相比,0.5%活性肥、0.5%复合肥、0.5%复合肥+0.5%活性肥处理对膝柄木苗高和地径有一定的促进作用,其中0.5%复合肥+0.5%活性肥处理对苗高和地径的生长均有极显著促进作用,0.5%复合肥处理对地径生长有极显著的促进作用、对苗高生长的促进作用不显著,0.5%活性肥处理对苗高和地径生长的促进作用均不显著。结论]0.5%复合肥+0.5%活性肥处理能有效促进膝柄木苗高和地径的生长。

Study of Fertilization Effect on Seedling Growth of Rare and Endangered Species Bhesa sinensis

Objective]To explore the effect of fertilization on Bhesa sinensis seedling growth.Method]One-year-old container seedlings of B.sinensis were used as research material, effects of different fertilizers and their combination on B.sinensis seedling height and ground diame-ter were studied.Result]Results showed that all fertilization treatments promoted the growth of B.sinensis seedling height and ground diame-ter.The combination of 0.5% compound fertilizer and 0.5% active fertilizer has significant promoting effect both on the B.sinensis seedling height and diameter growth.0.5% compound fertilizer has significant positive effect on ground diameter, but it has no significant effect on seedling height.0.5%active fertilizer has no significant effect on seedling height and diameter growth.Conclusion]The combination of 0.5%compound fertilizer and 0.5% active fertilizer has significant promoting on B.sinensis seedling height and ground diameter.
